Pressure Guage
Description
A pressure gauge is an instrument used to measure the pressure of gases or liquids within a system. These devices are crucial in various industries, including manufacturing, automotive, HVAC, and process control, to ensure systems operate within safe and efficient pressure ranges.
🔧 Types of Pressure Gauges
Pressure gauges come in several types, each suited for specific applications:
Bourdon Tube Pressure Gauge: Utilizes a curved tube that straightens under pressure, moving a needle on a dial. Commonly used for general-purpose pressure measurements.

Diaphragm Pressure Gauge: Employs a flexible diaphragm that deflects under pressure. Ideal for low-pressure measurements and corrosive media.
Capsule Pressure Gauge: Features two diaphragms welded together, forming a capsule that expands or contracts with pressure changes. Suitable for measuring low pressures of gases.
Absolute Pressure Gauge: Measures pressure relative to a perfect vacuum, providing accurate readings unaffected by atmospheric pressure changes. Used in high-precision applications.
